Why Monitor Brightness Numbers Need Context
A display can reach one brightness on a small highlight and a lower level across a mostly white screen.
Panel electronics and heat management affect how much light a monitor can sustain. Some displays briefly boost small highlights while limiting brighter areas that cover more of the screen.
Room reflections and viewing angle can change perceived contrast. A bright monitor can still be uncomfortable if glare crosses the part of the screen where text is read.
Test the kind of content you use most, such as a white document or a dark game with flashes. Measure or compare the display after it has been showing that content for a while.
